Short- and long-term outcomes of robotic- versus laparoscopic-assisted right hemicolectomy: A propensity score-matched retrospective cohort study

摘要

BACKGROUND: This study aimed to retrospectively compare the short- and long-term outcomes of robotic- and laparoscopic-assisted right hemicolectomies. MATERIALS AND METHODS: Patients who underwent right hemicolectomy with either robotic (46 patients) or laparoscopic (186 patients) surgery between January 2016 and December 2018 were analyzed retrospectively using propensity score matching (PSM). RESULTS: After matching, the robotic group included 45 patients (out of 46) and the laparoscopic group included 100 patients (out of 186). Compared to the laparoscopic group, the robotic group had shorter median times to first flatus (2 vs. 4 days; p < 0.01) and a liquid diet (4 vs. 5 days; p < 0.01) and shorter median postoperative hospital stays (7 vs. 8 days; p < 0.01). There were no significant differences in other short-term or oncological outcomes between the two groups. The 3-year overall survival and disease-free survival rates were equivalent. CONCLUSIONS: Robotic-assisted right hemicolectomy had the advantages of a quick recovery of bowel functions and an earlier postoperative discharge and was non-inferior to laparoscopic-assisted right hemicolectomy in all other outcomes.
